Probem while transmitting video on internet ???? dying for helpppppppp

hi,
i m using JMStudio from transmittion and JMStudio for receiving over the INTERNET but they cannot transmit and receive over the INTERNET can any one help me???
what can i do and from Where i can find RTP server for free.Help me please.
thanks inadvance

Here's a little progam that you can run on your 2 machines (server and client) to know their IP addresses :
public class IPAddress {
public static void main (String[] args) {
try {
System.out.println(java.net.InetAddress.getLocalHost().getHostAddress());
} catch (Exception e) {}
This IP addresses are used to indentify machines, so the IP address of server will be used for AVReceive2 and the IP address of client will be used for AVTransmit2. You can choose the port number ramdomly but it must be > 1024 and not already reserved by another internet service. This port number must be the same for AVReceive2 and AVtransmit2.
Note that you've to run the programs on 2 differents machines if you don't want to modify the AVTransmit2 code (to permit the use of another port for AVReceive2).
Good luck !

iam able to transmit video using RTP in the LAN but not in the internet.
what should i do to transmit the video over internet?.which ipaddress i need to use?
please help me.

hay guys,
the problem of video streaming through internet is solved.....
can any one have idea about converting H.263 format back to jpeg
thanks in advance

Capturing video to a file while transmitting it over the network

I have tried several ways to do this but non of them have worked. On the JMF Programmers Guide its stated that one could do something like this: creating a processor from a DataSource, and the taking two Datasources from the processor, one is used to transmitt the video over the network, and the other is used to save the data to a file(through a DataSink).
One of the ways I've tried is to clone de DataSource before creating the Processor. I've also tried to clone the Data source after creating and realizing the processor. The other way I've tried is by using the JMFSolution "Video Capture Utility with Monitoring", found at the jmf's homepage, which intercepts the data carried from the capture data source to the Processor.
Non of these have worked, and I always get Exceptions about not finding a DataSink for the DataSource I use. For example:
"javax.media.NoDataSinkException: Cannot find a DataSink for: com.sun.media.multiplexer.RawBufferMux$RawBufferDataSource@d9850" ;
"javax.media.NoDataSinkException: Cannot find a DataSink for: com.sun.media.vfw.PushBufferDataSource@1e45"
I've search the Web triying to find something clear about capturing video to a file while transmitting it over the network, but nothing seems to work.
I would appreciate a piece of an advice on this.

you can try modifing de Capture example from JMF Solutions.
change this function:
public int startCapture() {
     int result = -1;
     enableComponents(false);
     buttonStart.setLabel("Pause");
     buttonEnd.setEnabled(true);
     startMonitoring();
     try {
processor.start();
DataSource clone = Manager.createCloneableDataSource(datasource);
     MediaLocator ml2 = new MediaLocator("file://capture.mov");
System.out.println("Content Type " + clone.getContentType());
datasink = Manager.createDataSink(processor.getDataOutput(), ml2);
     datasink.open();
datasink.addDataSinkListener(this);
     datasink.start();
result = 0;
     } catch (Exception e) {
     System.err.println("DataSink Exception " + e);
result= -1;

View video from webcam while transmitting

Hi everyone, when I try to use AVTransmit3.java and Clone.java (example from sun) to see video from webcam while transmitting, an error occur:
{color:#ff0000}+java.lang.NullPointerException+
at com.sun.media.codec.video.colorspace.RGBConverter.process(RGBConverter.java:352)
at com.sun.media.BasicFilterModule.process(BasicFilterModule.java:322)
at com.sun.media.BasicModule.connectorPushed(BasicModule.java:69)
at com.sun.media.BasicOutputConnector.writeReport(BasicOutputConnector.java:120)
at com.sun.media.SourceThread.process(BasicSourceModule.java:655)
at com.sun.media.util.LoopThread.run(LoopThread.java:135){color}
So I'm only able to see in local my captured video, but cannot transmit.
I try to debug JMStudio to find how to do this(monitoring transmitted video), but I'm not able to debug it.
In method private String createProcessor() of AVTransmit3.java I added
//----------------------------------------------------Start
            clone = Manager.createCloneableDataSource(ds);
            if (clone == null) {
                System.err.println("Cannot clone the given DataSource");
                System.exit(0);
            Clone cloneV = new Clone();
            if (!cloneV.open(clone))
                System.exit(0);
//----------------------------------------------------End
     return null;
    }This is the clone.java from sun

I post all the class I use in this project.
Copy and create your own project (SERVER side)
Then on other pc (CLIENT side) run JMStudio and open RTP transmission: you will receive data but on server you will have a black window.
I've modified only AVtransmit3.java -> look at Main() and modify dest-ip and port.
JFrameMain is a class with a button to close the application.

After a week's worth of debugging, I found the issue.
The Java type returned from the call was defined as ArrayList. Changing it to List resolved the problem.
I'm not sure why ArrayList isn't a valid return type, I've been looking at the Adobe docs, and still can't see why this isn't valid. And, why it works in Debug mode and not in Release build is even stranger. Maybe someone can shed some light on the logic here to me.

Minimal internet speed for video chat?

Hi!
What is the minimal internet speed for using Video Chat?
Regards, Soaman
Leader of Ljubljana BlackBerry Developer Group
BlackBerry Certified Builder for Native Application Development

Hey soaman,
The only information I can find regarding this is that you need to be connected to WiFi in order to use the video chat.
Here are a few notes from the user guide:
I want to improve the chat quality: You or the person you are having the Video Chat with may not have a sufficiently strong Wi-Fi signal. Try a different Wi-Fi network with a stronger connection, or move closer to the wireless access point.
My chat was dropped: Try connecting to a different Wi-Fi network. You cannot switch Wi-Fi networks during a call.
Hope this helps.

Export settings in QT Pro for putting video onto Internet

Hi,
I'm new to Quicktime and the video arena so could use some advice. I have a couple of questions.
1) What is the ideal codec setting for exporting AVI video when you want to put short clips on the WEB? I had thought it was H264 but I was experimenting with a 10 sec AVI clip (shot with a WEBCam in 320x240, 25fps, 49M) and found exporting to QT Movie using H264 (keeping size same etc) gave a 2.5M file and when hinted for streaming gave a 5M movie. When I exported to movie and streaming using MPEG4 codec both files were about 900K. My IE browser plays both the streamed and movie files as well; not very sure the difference between streaming and movie in this context??
2) I've just purchased a 30G (5G) iPod with FW 2.1. Ideally I wanted it to show video on TV, and was interested in the 640x480 support thinking this would scale better to TV screen. Haven't used the iPod yet but was checking other discussions on this forum and it seems its not that easy in QT to export video in H264 @ 640x480 for playback on iPod. People tend to advise the export for iPod option which is 320x240 instead. iPod states support for 640x480 in H264 @1.5Mbs and MP4 @ 2.5M so what is the problem?

Hi JonnyB132,
Which formats have you tried? I would try H.264 first.
Thanks,
Kevin

Electrical power for iPod while watching videos...

I was wondering if there was a way to leave my iPod connected to my MacBook while watching videos on my TV so that the iPod draws power from my MacBook and not the iPod battery. I don't have a universal dock, so I don't want to completely drain my battery while watching the videos on my TV.

If you use an A/V cable from Apple or third party ( some thrird party cables require you to swich the yellow and red at TV) from iPod mini plug and get an Apple or third party power adaptor (which will work with your USB cable that came with the iPod) it should work fine.
As to playing Video and Music from iPod and using the your MacBook as the power source I think that would also work, it may be better to frist eject the iPod but leave it attached.
Why would you not just play stuff directly to TV from the MacBook and only use iPod when the laptop is not available?
The best way to do what you want is to get thhe A/V kit from Apple or a third party A/V dock and cable. There are several listed on the Apple store on this site or at iLounge (http://forums.ipodlounge.com/).

FCE Freezes while importing video

While importing video, FCE freezes, usually within 3-4 minutes of capture. I have to force quit. I am using Capture Now. I have no problem importing with iMovie. In fact I've been importing in to iMovie and then copying the clips into FCE to get around the freeze. I have my clips saved to a 500GB external drive and my camcorder is a Panasonic PVGS-300. I have imported into FCE many times before. This is the first time this has occurred and I haven't changed anything in my setup or added anything to the system. Any help would be greatly appreciated.
Thank you.

I'm having the same problem.
Yesterday, I captured 45 minutes in 4 minute sections, and spent the morning editing.
It got slower & slower & slower.
I saved all, quit & browsed the internet for a while.
The computer continued to whir for some time.
I went back into FCE & it was back up to speed.
I suspect imminent hard drive failure.
Does anyone have an opinion on my diagnosis?

Premiere EL 11 importing video from Internet

Hi,
I have been struggling undestanding how to properly manage video I download from the Internet and use in Premiere Elements 11.
Most of the time I download from youtube with "Youtube Downloader HD" hoping that this is a valid tool to use and a lot of times I end up with a ".flv" file. If you know of any better software please suggest. Unfortunately, Premiere El. does not import flv file (I hope very soon development team can add this file format too, if possible). So, I have to use another software I purchased called "WinX HD Video Converter Deluxe" to convert the file into avi. (I know that the first software already converts it into avi but wish to retain the original file format.)
I have PAL as live in Europe and would prefer 16:9 over 4.3 if possible, considering that most of the modern TV display are wide screen
1.This is the specs of the movie I downloaded from Youtube at 480p
First thing I notice is that I should have 25fps for PAL rather than 29.970029.
Question n. 01: when converting it into avi can I change frame per second into 25 or should I keep it as it is and in this case select 30fps?
(I ask this question for when I will import it into Premiere EL.)
Question n. 02: when I start a new project what do I select among the many selections (for PAL)? Can someone please provide me the full path from beginning "File/New/Project/Project Settings"?
Question n. 03: as previously stated I selected in Youtube 480p (which should correspond to Progressive Scan 480P 640x480). Howcome in the property of the movie (I obtained it from the VLC Player while playing the movie) reports being 854x470? What should I do?
Question n. 04: is AVI the best video format to convert for later on import into Premiere EL or not? If not, what do you advise me to select?
Last Question: Please it is so important: can someone list me some valid links where to learn about all video format commonly used and how to master this initial portion of the Premiere EL project?
This so that I will be able to manage and properly set correct project settings in future.
Thank you,
Spiro

Adobe maintains that the formats that go into Premiere Elements are those which come out of a camera. FLV does not and so it is not supported. I remember seeing this as an official response to a similar question (Can't find that thread)
To answer your questions to the best of my knowledge:
1. Do not change the output frame rate to 25 from an external software. I say this because there are many algorithms that convert a 30 fps to 25 (Which frames are dropped, what happens to P-frames, bidirectional frames etc.). And Adobe will best understand an algorithm that is theirs. So keep the frame rate to 29.97 when converting to DV-AVI
2. Convert the video to a project setting that Premiere Elements has. You want a Widescreen, so do a 16:9, 720x480, DV-AVI. This video when brought into Premiere Elements will switch the project automatically to the NTSC DV Widescreen
3. I don't know this. There are too many things that could have gone wrong. The downloader could have encoded differently, the original file would have been this resolution but youtube chose to "categorize" this as 480P since it is the closest preset for them. VLC could be showing it wrong. Cconvert it to DV-AVI and you will surely see some borders but should not really be an issue once viewed in Full screen. I personally stop noticing them after a while and it is not a pain, for me.
4. Use DV-AVI. Premiere Elements simply likes it

Sporadic Rotating Loss of Internet Connection for Just Some Devices

Hi,
We've been having a problem where one or two of our devices (phones, laptops, iPads, Apple TV) lose internet connection for 10-30 sec at a time, while the others are fine.
As best as I can tell it's a full loss of connection, not just something running very slowly due to us pushing the bandwidth limits. I've experienced the latter elsewhere and this manifests very differently. It will instantly and fully disconnect a person from an online game or drop a skype call without the accompanying prolonged lag or distortion of bottlenecked bandwidth.
It happens at all times of day, and does not seem related to our peak times of bandwidth usage, nor the general public's peak times of usage.
We should have enough bandwidh for our usage, and usually we do. Our system is 25/25 Mbps and during our peak use at most we would probably have 1 laptop gaming, 1 HD video stream, and 2 non-HD streams. However, like I said before, the problem seems unrelated to overall bandwidth usage. The same problem occurs even at midnight when our local usage is minimal.
Overall we have 6 laptops, 5 phones, an iPad, 2 microcell signal boosters, and Apple TV, in total connected to the FiOS. We have a property with tenants where the signal is distributed via 3 WiFi routers and one direct ethernet cable to my laptop, and one to the Apple TV.
It happens on devices that are both connected through the WiFi (wife's laptop, phones, iPad) and ethernet (my laptop, Apple TV). It can happen with devices that are a few unobstructed feet from the WiFi router. However, it anecdotely seems to happen more on our phones than laptops.
My hunch is it is something outside our local network. This is because our equipment and usage has basically remained unchanged over the last couple months. (We got one new microcell tower for a different carrier, one new wifi router, but overall same # of people and patterns of usage.) And yet the problem seems to be getting worse. Back in probably early November I don't remember this problem occuring at all.
My second best guess is there are more devices connected to the network than it can handle simultaneously, and it rotates which gets kicked off. Maybe this was occuring before but we didnt realize it.
My third guess is it has to due with signal interference with the various WiFi routers and microcell boosters. However, this seems less likely since it also affects devices connected via ethernet cables.
Any thoughts or advice is much appreciated! Thanks!
-Ned

Ok, so in the mean time we decided to upgrade our service so I've only tried this solution now.
My problem though now is I can log into 192.168.1.1, then give my verizon admin password, and then set my channel preference. That seems fine for changing the main network input and wifi router (call it A).
However, we have another wifi router (call it B) which is fed from A via a cable. I cannot figure out how to change B's wifi channel. Therefore I worry if we have only switched A, since A feeds B (as well as the 2 microcells) they will all still be on the same channel and therefore still interfering with each other.
I have tried www.routerlogin.net (and .com) as written on my netgear router and I get "http://searchassist.verizon.com/" telling me "Sorry, We could not find www.routerlogin.net". I have also tried logging into wifi router B via all the 192.168.1.X addresses I see listed on the Verzion account when I log in via 192.168.1.1 (in total I tried all the 192.168.1.[1-24] options).
Thanks for the help!

Do I need an internet connection for Apple TV?

Hey I want to buy an Apple TV but before I do, I need to know does it require an internet connection to work? Or can it work without one?
The advertisement or information Apple gives me seems like it doesn't need an internet connection, I'm under the impression that if I buy one all I need is to connect it to my television then connect wirelessly from my iPad to the Apple TV device. Then I can begin streaming content to my TV via the Apple TV product.
However I came across a thing telling me I needed an internet connection in order for it to work, but where our televisions are, either the wireless internet is weak to nothing, and is unreliable from that distance, I want to be able to simply connect and play but now it seems Apple is misleading me on the capability of Apple TV.
I want to stream YouTube from my iPad to Apple TV, putting my iPad in a stronger range area and connected to Apple TV stream it... Or more importantly play content I have already on my device i.e. Video podcasts like IGN's Daily Fix, and stream it directly through the Apple TV onto my TV.
Please list all relevant information and requirements and capability I would have with Apple TV? I'm no where near an Apple store so I'll have to buy online so I want to make sure the product will work like they say it's suppose to.

I have the same issue and couldn't find an answer either. The problem is that the Apple TV requires an internet connection if you want to AirPlay internet content from your iPhone to the Apple TV, e.g. if the Apple TV isn't connected to the internet somehow, then Netflix or Youtube won't AirPlay from the iPhone to the Apple TV. I don't have a "house" internet connection currently, and when I bought my iPhone I was assuming I just can use my unlimited data plan to watch Netflix movies on the iPhone and AirPlay it to the big screen. No luck here, yet!!!
You can use the iPhone Hotspot and connect the AppleTV to that Hotspot, but I have a 5GB limit and that will be depleted with 2 movies or so, so that doesn't work either. I also can use the Hotspot to connect to my MacAir, which works great and 5GB limit is not the issue if you don't use it for movies, online gaming etc. But you could run into issues if you have to download big files, like updating the OS etc. That is something you have to consider when you are cutting the home internet.
I tried to somehow have the Apple TV use the Hotspot internet connection to just have access to the internet but use the iPhone unlimited data plan to stream movies, but the problem is that Apple TV can only connect to 1 WiFi network at a time and while it is connected to the hotspot, you can't connect to another network for AirPlay your content. Also, the ethernet port on the Apple TV (if used) will be prioritized and then WiFi would be turned off, ruling out the possibility to use ethernet and WiFi simultaneously to have one connected to the network using AirPlay and one using the Hotspot internet access. I believe the real problem is that the Apple TV needs internet access (for verification purposes???) while using AirPlay, and if there is no internet access through the network you are using for AirPlay, it might not work, at least I couldn't find a solution for it yet.
I was reading that with iOS 8 there might be a new feature that uses Peer-to-Peer technology between iOS devices and Apple TV, that might enable that you can connect to Apple TV with Peer-to-Peer and also connect it with the iPhone Hotspot for internet access (I would assume that the data amount from just being connected to the internet would be minor if the streaming data comes from the data plan itself from the iPhone).
That said, I can still stream content from my iTunes library to Apple TV, which is stored on my computer and doesn't need to be downloaded or streamed (Not the content I have purchased. Some folks mentioned bought content still needs internet access). So you can use your content you already have on the computer by using your local network. I hope somebody can give a solution to that problem! I was hoping to never have to deal with cable or telephone companies ever again, just using my mobile carrier, but I might be out of luck!
P.S: I also tried to connect my MacAir with the iPhone hotspot and then share this internet connection from the MacAir with my Apple TV. Didn't work either :-(
